FIG. 1 is a diagram illustrating a system for audio output for each a plurality of applications, according to an example embodiment.

As illustrated in FIG. 1, a system for audio output for each of a plurality of applications includes a user terminal device 100 and a peripheral device 200.

The user terminal device 100 outputs audio of at least one of a plurality of applications via a speaker. This user terminal device 100 may be a portable terminal device, such as a smartphone and a tablet PC.

In addition, the peripheral device 200 may be a device which outputs audio received from the user terminal device 100. This peripheral device 200 may be an electronic device, such as a wearable device, a smart TV, a terminal device for vehicles, a speaker, and the like, which may communicate with the user terminal device 100.

In detail, the user terminal device 100, according to a user setting, outputs audio of a first application from among a plurality of applications via a speaker of the user terminal device 100, and transmits an audio signal of a second application to the peripheral device so that audio of the second application is output through a speaker of the peripheral device communicable with the user terminal device 100.

Accordingly, the user terminal device 100 may output audio of the first application, and the peripheral device 200 may output audio of the second application based on an audio signal received from the user terminal device 100.

For example, the first application may be a navigation, and the second application may be a media player. For these first and second applications, the user may set audio of the first and second applications to be output from each device. That is, the user may set audio of the first application to be output through a speaker of the user terminal device 100 and set audio of the second application to be output from the peripheral device 200 which may communicate with the user terminal device 100. In this regard, the peripheral device 200 may be a terminal device for vehicles which is mounted on a vehicle and outputs car audio.

In a state in which devices to output audio of the first and second application are set, when an execution command of the first application is input, the user terminal device 100 may display an execution screen of a navigation and simultaneously, output navigation-related audio via a speaker of the user terminal device 100.

In a state in which a navigation is executed, when a command to execute the second application is input, the user terminal device 100 executes a media player, which is the second application, and transmits an audio signal for music reproduced through the executed media player to the peripheral device 200 found as a communicable device. In this regard, the peripheral device 200 which has been found as being communicable may be a terminal device for vehicles which is set to be an apparatus to output audio of the second application. Accordingly, the peripheral device 200 may reproduce music for the audio signal received from the user terminal device 100 via a speaker mounted in the peripheral device 200.

Accordingly, the user who got on the vehicle may, while driving the vehicle through a navigation executed through the user terminal device 100, listen to music reproduced through a media player of the user terminal device 100 through the peripheral device 200 which is a terminal device for vehicles mounted on the vehicle.

Hereinabove, a system for audio output for each of a plurality of applications according to the present disclosure is briefly described. Hereinafter, the respective configurations of the user terminal device 100 according to the present disclosure will be described in greater detail.

In addition, the audio output unit 120 outputs audio of at least one of a plurality of applications that may be executed in the user terminal device 100 via a speaker of the user terminal device 100.

When an event occurs while audio of a first application from among a plurality of applications is output via the audio output unit 120, the control unit 130 controls the communication unit 110 to transmit audio of a second application corresponding to the event to a peripheral device 200 which is capable of communicating with the user terminal device 100.

In this regard, the control unit 130, while audio of the second application is transferred to the peripheral device 200 which is capable of communicating with the user terminal device 100 via the communication unit 110, controls the audio output unit to constantly output audio of the first application via a speaker. Accordingly, the audio of the second application can be output via the peripheral device 200 while maintaining output of the audio of the first application.

According to an additional aspect of the present disclosure, when a communicative connection with the peripheral device 200 which outputs audio of the second application is released, the control unit 130 searches for at least one other peripheral device 200 which is capable of communicating with the user terminal device 100. When another peripheral device which is registered from among at least one other peripheral device is present, the control unit 130 controls the communication unit 110 to transmit an audio signal of the second application to the second peripheral device 200. Accordingly, the communication unit 110 transmits an audio signal of the second application to the second peripheral device 200.

When an audio signal for the audio of the second application is received from the user terminal device 100, the second peripheral device 200 may signal-process the received audio signal in a form capable of being output and then, output the signal-processed audio of the second application via a speaker within the second peripheral device 200.

As illustrated in FIG. 3, the user terminal device 100 may further include a display 140 for displaying a UI to set a device to output audio of each of a plurality of applications. In this regard, for a UI to set a device to output each of the plurality of applications, icons of the plurality of applications and icons of devices from which audio of the plurality of applications is output may be mapped with each other.

In a state in which this UI is displayed, when an icon of the second application is selected, the control unit 130 controls the display 140 to display an icon for at least one device which is capable of outputting audio.

Accordingly, the display 140 displays a UI including the icon for at least one device which is capable of outputting audio of the second application. In a state in which a UI including an icon for at least one device which is capable of outputting audio of the second application is displayed, when at least one icon is selected, the control unit 130 may set a device corresponding to the selected at least one icon to a device to output audio of the first application.

When a peripheral device 200 to output audio of the second application is not registered, when a user command for volume adjustment is input, the control unit 130 controls the display 140 to display a UI for an application to output audio through a speaker of the user terminal device 100 from among applications that are executed. Accordingly, the display 140 may display a UI for at least one application set to output audio through a speaker from among the applications that are executed.

In a state in which a UI for at least one application set to output audio through a speaker from among these executed applications is displayed, when at least one application is selected, the control unit 130 controls the display 140 to display an icon for at least one device which is capable of outputting audio of the selected application.

Accordingly, the display 140 displays a UI including the icon for at least one device which is capable of outputting audio of the selected application.

In a state in which a UI including an icon for at least one device which is capable of outputting audio of the selected application is displayed, when at least one icon is selected, the control unit 130 may change a device corresponding to the selected at least one icon to a device to output audio of the corresponding application.

While audio of the second application is output through the peripheral device 200, when an event that a third application set such that audio is output from the corresponding peripheral device 200 is executed occurs, the control unit 130 controls the display 140 to display a UI for resetting audio of the third application.

Accordingly, the display 140 displays a UI including the icon for at least one device which is capable of outputting audio of the third application. In a state in which a UI including an icon for at least one device which is capable of outputting audio of the third application is displayed, when at least one icon is selected, the control unit 130 may change a device corresponding to the selected at least one icon to a device to output audio of the third application.
